DELIVERY-STAND FOR ROLLED M ATERIAL.

To aZLwhom it may concern:

Be it known that I, SAMUEL M. LANGSTON,

in the county of Gloucester, and State of lVew Jersey, have invented certain new and useful Improvements in Delivery-Stands. for- Rolled Material, of which the following is a specification.

This invention is adapted for use with or as a part of any kind of machine which receives, feeds, or operates on sheet material taken from a large or heavy .roll. The machine may be any kind of a paper working machine for printing, corrugating, embossing, slitting, scoring, folding, pasting, rerolling, or otherwise treating the sheet material withdrawn from the rotatably supported roll.

Among the important objects of my invention are to reduce the labor required in lifting the roll of material to delivery position, to reduce the time consumed in changing to a new roll when a previous one is used up, to permit a full roll to be brought into operative position before the previous one is exhausted, to facilitate the adjustment of the roll axially after it has been raised, and if desired, while the material is ,being delivered therefrom, and to provide. the desired tension on the unrolling material which will operate the same irrespective of the degree of elevation or the extent of.

axial adjustment of the roll.

Only a part of these objects may be secured in some embodiments of my invention. In other words, certain features may 'be omitted without detracting-from the desirability or satisfactory operating of other features but in a preferred embodiment, all

of these objects are secured and .various other important andvaluable features are employed, which will be referred to more particularly hereinafter. 1 In the accompanying drawings, I have shown merely one form which my invention may assume and which is designed for supporting large heavy rolls of paper weighing more than one man can conveniently lift.

In these drawings: Figure 1 is an end elevation of the machine. a

Fig. 2 isa front view of one end of the machine.

ing spaced means for engaging with the shafts of the paper rolls and lifting them to the desired elevation and supporting them so elevated while the material is being unwound from the shaft. Means are provided for axially adjusting the roll and its shaftto insure the proper feeding of the material to the paper working machine, and

means are also provided for applying the desired tension to the sheet material. The roll may he raised barely clear of the floor and the. sheet material deliveredfrom the roll in this position until a considerable por tion of the roll has been used and the weight materially lightened, and it may then be raised to an elevated position while the ma.

'terial is being fed from the roll and a new roll brought into position, and raised clear of the floor ready for immediate use when the first roll is exhausted. Speed reducing gearing is employed for operating the elevators'or endless conveyers so that one man may very easily, operate the mechanism to raise a very heavy roll.

More specifically the particular machine illustrated in the accompanying drawin s includes a pair of end frames 10, rigidIy connected by a base or transverse frame member 11 so positioned that it does not interfere with the rolling or wheeling of a roll of paper intopo'sitionjreadyto be elevated. Each frame member 10 has a laterally extending or offset flange 12 rigid or integral therewith and carrying a conveyer support and guide. This conveyer support and guide is shown as a frame member 13 substantially H or X-shaped in cross section as shownparticularly in Fig. 3 and extending in an upwardly and inclined position as shown in Fig. 1. The web portion is cut away or omitted at the ends to receive sprocket wheels 14 supported on upper and lower parallel shafts. 15 and 16. The frame guide surfaces 17 substantially parallel on member 13 presents a pair of spaced endless opposite sides of the plane of the sprocket wheels, and each including curved portions substantially co-axialwith the sprocket wheels and longitudinally extending portrons tangential to the curved portions. The

lower sprocket wheels at 'the two ends ofthe machine, while at the upper end the shaft 16 preferably extends all the way across from one frame member 13 to the other so that by the rotation of this shaft 16, the two pairs of sprockets and their chains may be operated simultaneously. For conveniently and easily rotating this shaft irrespective of the load which may be carried by the chains or conveyers 19, I rovide suitable speed reducing gearing. his

is shown as including a large gear 21, mesh- ,ing with a pinion 22, on a stub Shaft 23 --mounted in a bracket 24 on one end frame 10. This stub shaft also carries a large gear 25 meshing with a pinion 26 on a second and lower stub shaft 27 which ma also be tation of the gears and conveyers.

mounted in the same bracket 24.

is connected to anyjsuitable source of power, as forinstance, a hand crank 28, and means are provided for preventing the reverse ro- Such means is illustrated as a pawl 29 engaging with the pinion 26 andhaving a weighted end 30, normally holding it in operative engagement with the teeth of the pinion. The speed reducing gearing permits one man to conveniently turn the crank 28 and lift a roll Weighing many hundreds of pounds;

For detachably connecting the chain to the roll supportingshaft, each chain has one or more, preferably 3' brackets 31 secured to the links thereof. Eachbracket has a base portion 32 for engaging with the guiding surfaces 17 upon opposite sides of'the chain.-

The connection between the bracket and the link is preferably adjacent to one'end of this base so that the bracket will be pulled up along the inclined guide. The bracketis -wider than the frame member '13 and has n locking the roll on the shaft andholdlng the two concentric. I have shown the shaft as- -depending flanges on its sides carrying inwardly extending lugs 33, engagin beneath the flanges 20 to hold the bracket 1n proper guiding relationship during its downward as well asits upward course. These lugs are preferably removable and are held inplace his shaft by any suitable means, as for instance, by set-screws so that the bracket may be readily taken off or replaced. The bracket has an open-sided or hook-shaped recess 34 adapted to receive the roll supporting shaft 35 and to pick up the shaft when the roll is brought into proper position in respect to the machine and the chain is operated to swing. the bracket beneath the lower sprocket and to the position shown at the lower right-hand corner of Fig. 1. One end of the'shaft preferably has a rack bar portion 36 formed of annular grooves, separating the circular rack bar teeth, and the bracket carries a pinion 37 meshing with this rack bar portion. As the shaft comes into the socket or recess 34, the rack. bar portion automatically comes into engagement with the pinion 37. This pinion is shown as mounted on a small stub shaft 38, having a handle 39, wherebyit may be rotatcd. to move the shaft endwise in either direction to the desired extent.

To prevent the free'rotation of theroll.

to provide the desire frictional resistance. This is shown as a screw bolt 44 pivoted to the brake-shoe 41 and extending through a slot in thebrake-shoe 42 and having a tightening nut 45., I

To prevent free rotation of the brakeshoes'with the brake-drum and at the same time to permit of a free axial adjustment of the shaft and the brake drum, which; is rigidly secured to the latter, a non-rotatable.

but axially slida'ble connection is effected between one of the brake-shoes and the bracket 31. This is shown in theform of a lug or projecting arm 46 carried ;.by the bracket substantially parallel to the roll supporting shaft 35 and in the Kath of a lug 47 on one of the brake-shoes.

his engagement of the .1 lug 47 with the arm or .projection 46 prevents the rotation of thebrake-shoes but does. not' interfere with the axial adjustment ofthe shaft 35 by means ".of the pinion 37 as the lug 47 may slide along the projection 46.

Any suitable means may be employed for the ends of the roll of'paper, and when hanger and similar collars 56 on the stop hanger.

forced to the limiting position, they may be I or any other suitable shaft; This means Iis shown as a pair. of

hangers between the two end frames and inthe path of the shaft 35'. Each hanger has an'jnclined downwardly extending upper surface beginning at a point substan-.

tiallydirectly above the upper shaft 16 and terminating in a hook-end 51 which receives and retains the shaft as the latter rolls downthe incline. A simple andefiicient meansfor supporting these hangers and permitting of their ready removal and adjustment .to-

.ward and from each other, is to hook them over the shaft 16 and lock them against rotation with the shaft. As shown, each hanger -5 has a downwardly facing recess or socket 52 receiving the shaft 16 and a lower laterally facing socket 53 receiving a. stop 54 rigidwith the frame of the machine.

This stop is shown in the form of a rod extending transversely of the machine, parallel to the shaft 16, and somewhat below the latter.. The hangers may behooked over the shaft 16 and their own weight will swing their outer ends downwardly and bring the sockets 53 in their lower inner ends into engagement with the stop54. To hold the hangers against any-axial movement along the shaft and to ins'urethe proper positioning of-them, suitable collars 55 'may be secured to the shaft 16 upon each side of eacg r0 at each side 'of the lower end 0 These may be secured in place in any'suitable manner, as for instance, b set screws and permit the free rotation o the shaft .16 during the raising of a roll without disturbing the position ofth'e hangers; From the foregoing description of the con-- struction, it is thought that the operation of the machine will be readily apparent, al-

though this operation .may be briefly described as follows. The operatorv first extends the shaft 35 throughthe roll of, paper and drives in the conical wedges 48 so as to hold the two rigid in respect to each other. The roll is then brought to the properposition in respect to the apparatus either. by

rolling it along the floor: or by conveying it on. a'truck until the .shaft comes to ap-'- the wise in'either direction andto any desired slight distance required to bring it over into the recesses or sockets 34.. The'crank28 is then further rotated to lift the roll, clear of the floor or-truck and the roll is then adjusted. endwise to bring it into proper alinement with the machine to which the paper is to be fed. This is done by turning the I pinion 37- by means of the handle 39. While this new roll is being brought into position and. adjusted, the machine may continue op- .75

erating, and taking paper from the roll. on the shaft in a more elevated position, as for instance, as shown at the upper right-hand side of'Fig. 1. When the upper roll is \ex-'. hausted, it is merely necessary to connect the, last end of the paper to the beginning end of the paper on the lower roll, and very little interruption in the machine is necessary to accomplish\this result. The roll of paper may be continuously fed from thefroll in itslower position until it is nearly used up orit may be raised at any time by turning the crank, 28. It should be raised before it is entirely exhausted so that a new roll may be brought into operative position on the next pair of '9 thehanger and be retained by-the hooks, 51 g i until the operator removes it therefrom and attaches ,it to the next roll bf paper. While the material is being delivered from the roll, the roll and its shaft may be adjusted endextent to maintain the proper alinement of the roll with the machine. to which it is dea livering. Rolls are often dished at one end i and frequent endwiseadjustmentof the roll is necessary to keep the paper in proper "alinement. This may be veryeasily and conveniently done any time by the rotation ofthe pinion 37. As previously pointed out,- suchendwise adjustment does not affect the 'proper action of the tensioning means which is carried solely by the shaft but which auto matically comesinto operative engagement increased or decreased at will during the deliveryof the paper and the tensioning means automatically disengages itself from the stop or arm 46 when the shaft leaves the bracketand rollsout on the hanger 50.
